Unlike a Troll, who deliberately intends to cause maximum disruption and argument, An Accidental Troll, is a normal user who speaks their mind a little TOO much through forums, and accidentally gives off the impression that they are a Troll, when clearly, they have little/no time and have a lot to say about the topics that are being posted.

BobMoney63: Hey, that guy is Trolling, ban his ass!

Admin: Nah, I've read through his posts, he's an Accidental Troll. He just has a lot of time on his hands, and has a lot to say about the topics that are being posted.
